The Honda CB750 is an air-cooled, transverse, in-line-four-cylinder-engine (excluding 2023- models) motorcycle made by Honda over several generations for year models 1969–2003, 2007, and 2023-present with an upright, or standard, riding posture. It is often called the original Universal Japanese Motorcycle (UJM).
The CR750 is the associated works racer.
Though other manufacturers had marketed the transverse, overhead camshaft, inline four-cylinder engine configuration and the layout had been used in racing engines prior to World War II, Honda popularized the configuration with the CB750, and the layout subsequently became the dominant sport bike engine layout.
The CB750 is included in the AMA Motorcycle Hall of Fame Classic Bikes; was named in the Discovery Channel's "Greatest Motorbikes Ever"; was in The Art of the Motorcycle exhibition, and is in the UK National Motor Museum. The Society of Automotive Engineers of Japan, Inc. rates the 1969 CB750 as one of the 240 Landmarks of Japanese Automotive Technology.
The CB750 was the first motorcycle to be called a "superbike".
